Water spinach grows very fast, about 15 days, and grows to about 10 cm. The most important work in this period is thinning and fixing seedlings.

When introducing the sowing technology, we have said that the planting density of water shield has a great influence on its growth, so when the seedlings grow to 10 cm, they should be interplanted in time. After the seedlings are fixed, the plant spacing and row spacing of small leeks are kept at about 5 to 7 cm.

Management of Ipomoea aquatica in the middle growth stage. When the water spinach grows to about 20 cm, it needs to be interplanted again. This is to make the small water spinach have a beautiful plant type. After this interplanting, the plant spacing between Ipomoea aquatica reached about 10cm. If this plant spacing is maintained, the small water spinach can grow upright.
